What drives the bidirectional relationship between metabolic and mental ill-health?

Read our new metabolic psychiatry paper, “An interoceptive model of energy allostasis linking metabolic and mental health” www.science.org/doi/10.1126/... led by @saramehrhof.bsky.social @hugofleming.bsky.social

An interoceptive model of energy allostasis linking metabolic and mental health

Interactions between metabolic interoception and regulation may drive comorbidity between mental and metabolic ill-health.

Does what you eat really shape your brain, and mental health? Or is it the other way around? Come discover how metabolism links body, brain, and mood with @camillanord.bsky.social at the Arches London Bridge for a SeedTalk on 30 September www.eventbrite.co.uk/e/metabolism...

New qualitative paper! A foray into gastric interception. @lucysta02475610.bsky.social ran a LOT of focus groups, across groups with eating disorders, gastric disorders and neither, to understand how people experience the sensations from their GI system. www.sciencedirect.com/science/arti...

In this @cp-trendsneuro.bsky.social Spotlight, I describe how a recent paper by @leahbanellis.bsky.social, @brainandstomach.bsky.social, et al. opens new avenues in interoception research, including those focussed on the subjective interpretation of internal signals: www.cell.com/trends/neuro...

Stomach–brain synchronisation is associated with poorer mental health

In common parlance, ‘being in touch with your body’ is often used positively. However, in a recent study, Banellis, Rebollo, and colleagues show that better stomach–brain synchronisation is actually a...

I'm looking for ~25 more people with a gastrointestinal disorder to complete an online survey on interoception. You can find this survey here: sites.google.com/york.ac.uk/l...

However, if autistic individuals present parkinsonian symptoms due to their autistic traits alone, clinicians should incorporate this knowledge into diagnostic assessments to prevent misdiagnosis. 🧵10/n

Lydia Hickman @lydiajhickman.bsky.social · Jun 16

Identifying the cause of the increased PD diagnosis prevalence in autism is important for the adaptation of diagnosis procedures. If autistic individuals are indeed more likely to develop PD, all stakeholders should be aware of this to ensure a prompt diagnosis. 🧵9/n

Lydia Hickman @lydiajhickman.bsky.social · Jun 16

Finally, we consider other potential explanations for overlap between autism and PD, including potential biological mechanisms (dopamine?🧠), as well as the contribution of antipsychotic medications in autism 💊. 🧵8/n

Lydia Hickman @lydiajhickman.bsky.social · Jun 16

Separate research studies highlight similarities between autism and PD across both gross and fine motor function, as well as emotion expression and recognition, theory of mind ability and cognitive rigidity. Direct comparisons in a matched-groups design are need to validate these conclusions. 🧵7/n

Given that PD diagnosis is primarily movement-based, if it is the case that autistic movement appears parkinsonian, this may facilitate autistic individuals meeting diagnostic criteria for PD. 🧵6/n

Lydia Hickman @lydiajhickman.bsky.social · Jun 16

We suggest that a newly emerging body of literature - movement differences in autism - may shed light upon this question. In the case of bradykinesia, postural instability and gait differences (core diagnostic features of PD), differences in autism have been explicitly likened to that of PD. 🧵5/n

Lydia Hickman @lydiajhickman.bsky.social · Jun 16

Why might this be the case? Genetics studies link some PD risk genes to autism 🧬, but a significant polygenic overlap is not apparent, and first-degree relatives of autistic individuals don't have elevated PD diagnosis rates. So can this relationship really be driven by genetics alone? 🧵4/n

Lydia Hickman @lydiajhickman.bsky.social · Jun 16

Conducting PD assessments in autistic groups also demonstrates high levels of PD traits. Starkstein et al (2015): 32% of their test sample screened positive for parkinsonism via UPDRS. Geurts et al (2022): 17% and 33% positive screening via PSQ in Netherlands and US samples. 🧵3/n

A number of recent studies have evidenced elevated PD diagnosis rates in autism. E.g., Croen et al (2015): 0.93% PD prevalence in autistic sample vs 0.03% in non-autistic sample. Hand et al (2020): 6.6% in autistic sample vs 1.2% in non-autistic sample. 🧵2/n
